Program Visualization for Debugging: A Multimedia Approach
This presentation explores software visualization for debugging, utilizing algorithm animation, typographic source code presentation, and interactive auralization to enhance the debugging process. The use of graphical and auditory representations aids in debugging, making it more accessible and engaging for programmers. Evaluation of tools like LogoMedia reveals both benefits and challenges, prompting open questions about the effectiveness and usability of these visualization techniques for both novice and expert programmers.

Software Visualization for Debugging Representing programs through algorithm animation, typographic source-code presentation, and interactive auralization transforms the hunt for bugs into a cognitively accessible multimedia experience. Ron Baecker Chris DiGiano Aaron Marcus Presented by Maryam Arab
Idea Claim: Graphical and auditory representations of programs are useful in debugging Visualization approaches: Algorithm animation 30-minute film to demonstrate the power of algorithm animation Source code pr sentation design of computer program source text can enhance the program s readability Interactive auralization for debugging LogoMedia interactive construction of visualizations during program creation and debugging Auralization is the process of rendering audio data by digital means to achieve a virtual three- dimensional sound space.
Evaluation Users tends to use LogoMedia to: assess the values of variables at particular points in programs monitor arbitrary changes to variables by mapping their values to sound monitor acoustical variables: loop indices Lists Counters Problems with LogoMedia: Simultaneous sound Lack of tracking a dataflow for non-defined variables
Open Questions Is either of the proposed ideas helpful? Do programmers have the patient to go through the visual or acoustic interfaces? Is it for only novices? Or experts can take advantage of it?
